Fix the things that are causing the most pain to new users ---------------------------------------------------------- 1. A new import is tagging all messages as "inbox" -- total pain 2. Allow an easy way to get tags from directory names (if the user has them) 3. Fix Xapian defect #250 so tagging is fast. Emacs interface (notmuch.el) ---------------------------- Enhance '+' and '-' in the search view to operate on an entire region if set. Fix '*' to work by simply calling '+' or '-' on a region consisting of the entire buffer. Add a global keybinding table for notmuch, and then view-specific tables that add to it. Add a command to archive all threads in a search view. Add a '|' binding from the search view. When a thread has been entirely read, start out by closing all messages except those that matched the search terms. Add support for choosing from one of the user's configured email addresses for the From line. Make 'notmuch-show-pipe-message have a private history. Add support for a delete keybinding that adds a "deleted" tag to the current message/thread and make searches not return deleted messages by default, (unless the user asks explicitly for deleted messags in the search query). Add support to "mute" a thread (add a "muted" tag and then don't display threads in searches by default where any message of the thread has the "muted" tag). Portability ----------- Fix configure script to test each compiler warning we want to use. Completion ---------- Fix bash completion to complete multiple search options (both --first and *then* --max-threads), and also complete value for --sort= (oldest-first or newest-first). notmuch command-line tool ------------------------- Implement "notmuch search --exclude-threads=" to allow for excluding muted threads, (and any other negative, thread-based filtering that the user wants to do). Fix "notmuch show" so that the UI doesn't fail to show a thread that is visible in a search buffer, but happens to no longer match the current search. (Perhaps add a --matching= option (or similar) to "notmuch show".) Teach "notmuch search" to return many different kinds of results. Some ideas: notmuch search --for threads # Default if no --for is given notmuch search --for messages notmuch search --for tags notmuch search --for addresses notmuch search --for terms Add a "--format" option to "notmuch search", (something printf-like for selecting what gets printed). Add a "--count-only" (or so?) option to "notmuch search" for returning the count of search results. Give "notmuch restore" some progress indicator. Until we get the Xapian bugs fixed that are making this operation slow, we really need to let the user know that things are still moving. Fix "notmuch restore" to operate in a single pass much like "notmuch dump" does, rather than doing N searches into the database, each matching 1/N messages. Add a "-f " option to select an alternate configuration file. Fix notmuch.c to call add_timestamp/get_timestamp with path names relative to the database path. (Otherwise, moving the database to a new directory will result in notmuch creating new timestamp documents and leaving stale ones behind.) Fix notmuch.c to use a DIR prefix for directory timestamps, (the idea being that it can then add other non-directory timestamps such as for noting how far back in the past mail has been indexed, and whether it needs to re-tag messages based on a theoretical "auto-tags" configuration file). Make "notmuch new" notice when a mail directory has gone more than a month without receiving new mail and use that to trigger the printing of the note that the user might want to mark the directory read-only. Also make "notmuch new" optionally able to just mark those month-old directories read-only on its own. (Could conflict with low-volume lists such as announce lists if they are setup to deliver to their own maildirs.) Allow configuration for filename patterns that should be ignored when indexing. notmuch library --------------- Index content from citations, please. Provide a sane syntax for date ranges. First, we don't want to require both endpoints to be specified. For example it would be nice to be able to say things like "since:2009-01-1" or "until:2009-01-1" and have the other endpoint be implicit. Second we'd like to support relative specifications of time such as "since:'2 months ago'". To do any of this we're probably going to need to break down an write our own parser for the query string rather than using Xapian's QueryParser class. Make failure to read a file (such as a permissions problem) a warning rather than an error (should be similar to the existing warning for a non-mail file). Add support for files that are moved or deleted (which obviously need to be handled differently). Actually compile and install a libnotmuch shared library. Fix to use the *last* Message-ID header if multiple such headers are encountered, (I noticed this is one thing that kept me from seeing the same message-ID values as sup). Add support for the user to specify custom headers to be indexed. Add support for configuring "virtual tags" which are a tuple of (tag-name, search-specification). The database is responsible for ensuring that the virtual tag is always consistent. Indicate to the user if two files with the same message ID have content that is actually different in some interesting way. Perhaps notmuch initially sees all changes as interesting, and quickly learns from the user which changes are not interesting (such as the very common mailing-list footer). General ------- Audit everything for dealing with out-of-memory (and drop xutil.c). Write a test suite. Achieve 100% test coverage with the test suite. Investigate why the notmuch database is slightly larger than the sup database for the same corpus of email. Xapian ------ Fix defect #250 replace_document should make minimal changes to database file http://trac.xapian.org/ticket/250 It looks like it's going to be easy to fix. Here's the file to change: xapian-core/backends/flint/flint_database.cc And look for: // FIXME - in the case where there is overlap between the new // termlist and the old termlist, it would be better to compare the // two lists, and make the minimum set of modifications required. // This would lead to smaller changesets for replication, and // probably be faster overall So I think this might be as easy as just walking over two sorted lists looking for differences. Note that this is in the currently default "flint" backend, but the Xapian folks are probably more interested in fixing the in-development "chert" backend. So the patch to get upstreamed there will probably also fix: xapian-core/backends/chert/chert_database.cc (I'm hoping the fix will be the same---an identical comment exists there.) Also, if you want to experiment with the chert backend, compile current Xapian source and run notmuch with XAPIAN_PREFER_CHERT=1. I haven't tried that yet, but there are claims that a chert database can be 40% smaller than an equivalent flint database. Report this bug: "tag:foo and tag:bar and -tag:deleted" goes insane This seems to be triggered by a Boolean operator next to a token starting with a non-word character---suddenly all the Boolean operators get treated as literal tokens)
